Elevated white blood cell count
ICD-10 D72.82 is a billable code used to indicate a diagnosis of elevated white blood cell count.
Elevated white blood cell count, or leukocytosis, is a condition characterized by an increase in the number of white blood cells (WBCs) in the bloodstream. This elevation can be a response to various physiological and pathological stimuli, including infections, inflammation, stress, and malignancies. Neutrophils, a type of white blood cell, are often the predominant cells involved in this condition, particularly in response to bacterial infections. Disorders of white blood cells can include leukemias, lymphomas, and myelodysplastic syndromes, which may present with abnormal WBC counts. Spleen disorders, such as splenomegaly or hypersplenism, can also affect WBC counts by sequestering or destroying these cells. Additionally, immunodeficiencies, whether congenital or acquired, can lead to abnormal WBC counts, as the body struggles to mount an adequate immune response. Accurate diagnosis and management of elevated WBC counts require a thorough clinical evaluation, including a complete blood count (CBC) and possibly bone marrow analysis, to determine the underlying cause and appropriate treatment.
Detailed lab results, including CBC and differential counts, and clinical notes explaining the rationale for testing.
Patients presenting with unexplained fever, infection, or fatigue requiring evaluation of blood counts.
Ensure that all relevant lab findings are documented to support the diagnosis of elevated WBC count.
Comprehensive history and physical examination, including any relevant imaging studies and pathology reports.
Patients with suspected hematological malignancies presenting with abnormal blood counts.
Documentation must clearly indicate the relationship between elevated WBC counts and any malignancies.
Used to evaluate elevated WBC counts in patients presenting with symptoms of infection.
Ensure that the clinical indication for the CBC is documented.
Hematology specialists may require additional tests based on CBC results.
Common causes include infections, inflammation, stress responses, and hematological malignancies. Each cause may require different diagnostic approaches and treatments.
